Age distribution of dengue cases in southern Vietnam from 2000 to 2015.
Background Dengue is the most common vector-borne viral infection. In recent times, an increase in the age of cases with clinical dengue has been reported in the national surveillance system and published literature of Vietnam. This change not only alter the risk of transmission and disease burden i...
